Biography
William O'Brien was born in Mallow, County Cork, Ireland on 2 October 1852, a descendant of Edmund Burke and Edmund Spenser. In 1868, his family moved to Cork City, and he became actively involved in the Irish Republican Brotherhood before resigning in the mid-1870s due to his disillusionment with physical force Irish republicanism. In 1878, he met Charles Stewart Parnell at a Home Rule League meeting, and he was imprisoned alongside Parnell that October; he was released in April 1882 and became an Irish Parliamentary Party MP in 1883. He was frequently arrested due to his support for various Land League protests, but, following Parnell's death in 1891, he came to oppose Parnell's faction in Parliament and retired in 1895. He died in 1928 at the age of 75.
